[TenTec] GFCI problem when running high power

[rohre]

John,
I would try a ferrite bead on the wires of the GFCI.  But, since you
probably have more than one GFCI, that would imply if only one is faulting
off, that it is overly sensitive to RF.   I would just replace it with a new
one and see if that is sufficient to take care of the problem, and keep the
old one for an emergency spare.  It is hard to get an adequate safety rated
AC capacitor that also is an efficient RF bypass.  And, it might affect the
operation time constant on the GFCI.
